queue()

Invoke a function at some point in the future...

Syntax

// syntax #1: optional game object as third parameter
queue(functionName, delay[, gameObject]);
 
// syntax #2: optional string as third parameter
queue(functionName, delay[, str]);

Parameters

Syntax	Parameter	Type	Description	Game Version
All	functionName	String	A string containing the name of a global function to invoke.	3.1 Beta 1
All	delay	Number	You can optionally set a minimum amount of time (in milliseconds) before your function gets called. Delays should ideally be 500 or more, and never less than 100. If you don't specify this parameter, or specify 0 (zero), Warzone will choose a delay for you, usually the next game tick (100ms).	3.1 Beta 1
#1	gameObject	Game object	An optional game object that will be passed in to your function when it gets called. The object will automatically be refreshed with the latest game data. If the object gets destroyed, the associated queued call will be cancelled automatically.	3.1 Beta 1
#2	str	String	An optional string that will be passed in to your function when it gets called.	3.2

Return value

Value	Type	Description	Game version
`undefined`	Undefined	The function was successfully queued.	3.1 Beta 1
<error>	Error	Did you forget to specify functionName as a string?	3.1 Beta 1

Notes

Unlike setTimer(), queue() does not repeat. It will make a single call to the named function at a later frame in the game.

The function, when called, will be run in the context of the global scope ("this" will be the global scope).

Queued function calls persist the save/load cycle. You can therefore look at Saved game files to see what queued functions were defined at the time the game was saved.

When using syntax #1, if the game object is destroyed any queued function calls associated with it will be cancelled.

Example

Syntax #1: Call 'foo' on the next game tick, passing in a game object

function foo(gameObj) {
  // gameObj == someGameObject
}

queue("foo", 0, someGameObject);
// global function foo will be called next game tick (100ms)
// if someGameObject gets destroyed, the queued call will be cancelled

Call a function after 1 second, passing in a string as its parameter

function bar(str) {
	// str = "hello"
}

// note: this syntax is only available on Warzone 3.2 and above 
queue("bar", 1000, "hello");
// global function bar will be called after 1 second

Availability 3.1 B1+

Requires:

Warzone 3.1 Beta 1 and above
Syntax #2 added in Warzone 3.2
